Flower-like α-Co(OH)2 spherical nanoparticles were synthesized using cobalt chloride hexahydrate, sodium hydrooxide and ammonia water as raw materials at room temperature under the condition of no surfactant.The component, morphology and structure of α-Co(OH)2 nanoparticles were characterized with X-ray diffractometer (XRD), fourier transform infrared spectrometer (FT-IR) and field emission scanning electron microscopy (FESEM).The effect of flower-like α-Co(OH)2 nanoparticles on the thermal decomposition of ammonium perchlorate (AP) was studied by using differential scanning calorimeter (DSC).The results show that α-Co(OH)2 particles, which is a flower shaped structure composed of nanosheets, are spherical, its particle size is relatively uniform, and the diameter of the nanometer flower is 300-400nm.When the addition amount of α-Co(OH)2 is 3%(mass fraction),the decomposition temperature of AP is 281℃, decreases by 158℃ compared with pure AP, and the decomposition heat is 1502J/g, showing that flower-like α-Co(OH)2 has an excellent catalytic effect for thermal decomposition of AP.%以六水氯化钴、氢氧化钠及氨水为原料,在室温且不使用表面活性剂的条件下制备了纳米花状α-Co(OH)2球形颗粒;用X射线衍射仪(XRD)、红外光谱仪(FT-IR)和场发射扫描电子显微镜(FESEM)表征了α-Co(OH)2纳米花的组分、结构和形貌,用差示扫描量热仪(DSC) 研究了α-Co(OH)2纳米花对高氯酸铵(AP) 热分解性能的影响.结果表明,α-Co(OH)2为球形颗粒,粒径大小均一,是由纳米片组成的花状结构,纳米花的直径为300~400nm;当α-Co(OH)2纳米花质量分数为3%时,AP的分解温度为281℃,与纯AP相比提前了158℃,放热量达1502J/g,表明α-Co(OH)2纳米花对AP的热分解具有优异的催化作用.
